EnableDevices is (amongst others )called after a VT switch. We must not create
a new sprite or re-pair the device, otherwise we lose the input device setup
that we had before the VT switch.
This requires the devices to be in exactly the same order as before
the VT switch. Removing a device while on a different VT is probably a bad
idea.
The device state needs to be changed while processing the XI event. Core
events are always processed after XI, so by then the device is already set up
properly. However, we now rely on DeviceButtonMotionMask to be equal to
ButtonMotionMask. It already is, but stick a big fat warning in so nobody
attempts to change it.
This commit disables XKB for the VCK, thus essentially for all devices.
Temporarily anyway.
Add keyc->postdown, which represents the key state as of the last mieqEnqueue
call, and use it when we need to know the posted state, instead of the
processed state (keyc->down). Add small functions to getevents.c to query and
modify key state in postdown and use them all through, eliminating previously
broken uses.
over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
Add support for HAL-based hotplugging, in which we just get the list of
input devices and properties from HAL. Requires an FDI which is not yet
in mainline HAL.
Is set when passive grab is implicit as result of a ButtonPress event. If this
is the case, we need to store the XI mask as well as the core mask to ensure
delivery of XI events during the grab's lifetime.
Remove all core grabs on other devices when client issues a GrabPointer or
GrabKeyboard request. Let's assume that the client really only wants one
device to interact, so this seems like a reasonable solution.
Add XGE handling in DeliverGrabbedEvent.
We can now grab something selecting XGE events, but the current code is a
bit messy and doesn't work too well yet.
If we don't do this, a device that is paired before a sprite has been
initialized for the paired device will not actually get the right sprite and
segfault the server on focus events. Happens for the VCK.
Both VCP and VCK are not in the inputInfo.devices list anymore, so we need to
check them separately. If we don't do this, we end up re-using ids 0 and 1,
causing all sorts of grief for clients.
Requires moving the spriteTrace into the DeviceIntRec and adjusting a few
functions to take in device argument, most notably XYToWindow().
Cursor rendering on the second screen is busted.
arbitrary X status codes instead of just TRUE/FALSE.
The dix layer in most cases still does not propagate the return value of
XACE hooks back to the client, however. There is more error propagation
work to do.
Improve memory usage by allocating the sprite's memory only to devices that
actually have a sprite and provide means to remove a device's cursor from the
screen (more hotplugging, yay!).
This commit breaks ScreenRec's ABI.
The former <X11/extensions/XKBsrv.h> has been pulled into the server now as
include/xkbsrv.h, and the world updated to look for it in the new place,
since it made no sense to define server API in an extension header. Any
further work along this line will need to do similar things with XKBgeom.h
and friends.
EnableDevice.
zero out spriteTrace, otherwise GetCurrentRootWindow() may return
invalid data.
Evdev adds previously hotplugged devices on its own when rescanning,
and ActivateDevice does not get called for those devices. Sprites need
to be initialized or paired before the device gets started, so the
safest place to do so is EnableDevice (which actually does get called
by the evdev driver).
